Question

Make comparative sentences (short adjectives)

2. The winter- bad- the fall
3. A cheetah- fast- a lion
4. Arica- dry- Valparaiso
5. Brazil- big- Argentina
6. Tom- Silly- Jerry
7. Valdivia- Far- Temuco
8. River Plate- good- Colo-Colo

Answer 1

2. The winter is as bad as the fall./The winter is worse than the fall.
3. A cheetah is as fast as a lion./A cheetah is faster than a lion.
4. Arica is as dry as Valparaiso./Arica is drier than Valparaiso.
5. Brazil is as big as Argentina./Brazil is bigger than Argentina.
6. Tom is as silly as Jerry./Tom is sillier than Jerry.
7. Valdivia is as far as Temuco./Valdivia is further than Temuco.
8. River Plate is as good as Colo-Colo./River Plate is better than Colo-Colo.

Eu diria pra escolher, dentre as duas opções de frases que dei em cada uma, a mais concordante com a verdade, apesar de todas estarem certas.
Como por exemplo na "Brazil is as big as Argentina./Brazil is bigger than Argentina." ambas estão escritas da forma correta, mas eu diria para que usasse a "Brazil is bigger than Argentina", pois, de fato, o Brasil é maior que a Argentina, os dois não são do mesmo tamanho.

Espero ter ajudado. Caso tenha alguma dúvida, estou disposta a esclarecer!
